Ok so long story and a lot of *****ing short. Its best to just upgrade the rear sway bar. I'm going to be dropped on d2 in june... not that it matters. Was going to get the 04+ tl sway bar, Should i not get oem and go with progress?
The OEM TL-S bar is more than enough, Like I said My coupe oversteers pretty bad with just the rear bar, So be mindful, If Lift throttle oversteer is what you want just upgrade the rear.
I have no experience with the progress bar but have read good things.
Good luck
